Dichroic Filters reflect a range of wavelengths and transmit others based on the principle of interference, through deliberate engineering of dielectric coatings deposited and substrates, dichroic filters can realize precise selection of light. Because the filters split light into two components: a reflection component and a transmission component, a user can select spectral regions of interest and decide whether the separated light spectrum should be utilized or dumped. Because the unwanted portion of the light is reflected instead of absorbed by the filters, dichroic filters can endure light sources with higher intensities.
This catalog specifies Shalom EO's Dichroic Filters for RGB Laser Show, these dichroic filters offer combinations of exceptional transmittance and reflectance at red (650nm), green (532nm), blue(473nm) wavelengths. Multitude standard groupings of transmission and reflection of RGB wavelengths are available, while we also provide custom options. Various dichroic filters with wide operation wavelengths are also available in Hangzhou Shalom EO including long pass filters, short pass filters, dichroic bandpass filters, dichroic band stop (notch) filters, and filters for color correction. our dichroic filters serve as excellent components to separate color in CCD imaging, digital projection, light show, machine vision, and printing.
